Grodan® Stonewool Macro Plugs

MACRO PLUG BULK-ROUND W/SLIT (1EA=2000)

Macro Plugs have a slit that allows easy insertion of a cutting. These loose round plugs fit perfectly into the Gro-Block hole. For best results with these Macro Plugs, always insert them into a tray with individual cells. The individual cell will make sure that the plug stays closed around the stem of your cutting.
